xsl needed: sibilings with different parents

Hi,
 
I've the following document:
 
<root>
  <AA>
        <AA1/>
        <AA1/>
        <AA1/>
......
  </AA>
  <BB>
        <BB1/>
        <BB1/>
        <BB1/>
......
  </BB>
</root>
 
I need to loop on BB/BB1 and within the loop, I need
to use the index or position of BB/BB1 and access
AA/AA1 to get the corresponding AA/AA1's value each
time.
 
Any thoughts?
 
Thank you
